[PATCH v3 2/2] pxa/hx4700: Add PCMCIA/CF support

[Paul Parsons]

Add PCMCIA/CF support for the HP iPAQ hx4700. Underlying support is provided by
the pcmcia/pxa2xx_hx4700 platform_device implementation which hooks into the
existing pxa2xx-pcmcia driver.

V3:
Split into two patches: one for kernel drivers, one for hx4700 platform glue.
Rebased to linux-3.3-rc1.
